NEWS--Researchers have reconstructed atmospheric carbon dioxide levels over the past 2.1 million years in the sharpest detail yet, shedding new light on its role in the earth's cycles of cooling and warming. A first-ever analysis and comparison of the carbon footprints of different countries using a single, trade-linked model has been created by researchers at the Norwegian University of Science and Technology (NTNU) and the Centre of International Climate and Environment Research - Oslo (CICERO). ScienceDaily (June 22, 2009) — Some of the substances that are helping to avert the destruction of the ozone layer could increasingly contribute to climate warming, according to scientists from NOAA's Earth System Research Laboratory and their colleagues in a new study in the journal Proceedings of the National Academy of Sciences.
